Infinix Zero 40 review
The Zero 40 suits buyers who spend time outdoors (the bright screen is a genuine win), game casually, and want a thin phone that charges quickly without flagship costs. Anyone prioritizing display clarity on a large screen or expecting three-plus years of software updates should cross-shop rivals with 1440p panels and longer support windows.
This review is based on Infinix’s published specifications and public benchmark data for the Infinix Zero 40, and the rating is spec-based. GoSolo does not physically test devices; where we estimate real-world behaviour such as battery life or charge time, we say so. How we rate phones.
Overview
The Infinix Zero 40 pairs a bright 144Hz AMOLED display and thin build with a capable mid-range chipset and solid 45W charging, making it a compelling value play for buyers who want a modern, smooth phone without flagship pricing. Its main shortcoming is the lower FHD resolution on that large screen, which softens text and detail compared to 1440p rivals at similar prices.
Design & build
At 7.9mm and 195 grams, the Zero 40 feels refined and pocketable—a genuine strength for a phone with a 6.78-inch screen. The chassis balances thinness with durability: IP54 certification protects against dust and splashes, and Gorilla Glass 5 is standard for the class. There is a weight-versus-sturdiness trade-off here, but Infinix has landed it well. Colors (Rock Black, Violet Garden, Moving Titanium) are tasteful without being ostentatious.
Display
The 144Hz AMOLED panel is the phone's highlight. At 1300 nits peak brightness (high brightness mode), it is genuinely readable in direct sunlight, and the high refresh rate keeps scrolling and gaming silky. The drawback is resolution: 1080p on 6.78 inches gives 393 ppi, which reads as softer than the 1440p displays that rivals are now pushing into this price bracket. Text and fine detail lack the sharpness you would get on a 1440p AMOLED at the same size. If you spend hours reading or zoom into photos, the resolution gap will nag. For casual scrolling and video, it is fine.
Performance
The Dimensity 8200 Ultimate is a capable chip for 2024. It handles modern games (Genshin Impact, Call of Duty Mobile) at high settings and 60fps without throttling, and everyday apps open instantly. The Mali-G610 GPU is respectable, though truly demanding titles or sustained gaming marathons may force you into medium settings to avoid thermal slowdown. For browsing, messaging, and moderate multitasking, there is no sense of lag. The Dimensity 8200 is not a flagship processor—it sits a tier below Snapdragon's top chips—but it punches above entry-level and will remain relevant for the next 18 to 24 months. UFS 3.1 storage is fast enough that app launches and file transfers feel snappy.
Camera
The 108MP main sensor with f/1.8 aperture and OIS is solid for a mid-range phone. Low-light shots are sharper than they would be on a smaller f/2.0 aperture, and optical stabilization keeps video steady without excessive digital cropping. The 50MP ultrawide at 120 degrees is sharp for landscapes and group shots, though it cannot match the detail of flagship ultrawides. The 50MP selfie camera captures good detail in well-lit settings. Video maxes out at 4K@60fps, which is standard. The camera is capable rather than exceptional—it takes clean daytime shots and solid video, but it does not compete with flagship telephoto range or computational night mode wizardry. For social media and casual keepsakes, it is more than adequate.
Battery & charging
The 5000 mAh battery delivers roughly 18 to 22 hours under heavy use (gaming, streaming, navigation) and closer to 24+ hours with lighter use patterns. That is respectable but not exceptional for a modern phone of this size; you will want to charge daily if you game a lot. Wired charging is where Infinix shines: 45W gets you to 60% in 25 minutes and a full charge in around 40 to 50 minutes, which beats most rivals in this price range and approaches budget-friendly flagship speeds. Wireless charging tops out at 20W, which is slow in comparison and feels like a missed opportunity given the strong wired performance.
Software & support
The phone ships with Android 14 and Infinix's XOS 14.5 overlay. XOS is light and does not add much bloat, though Infinix promises only two major Android version updates—shorter than flagship brands offer. Realistically, that means you will be off mainstream support by late 2026 or early 2027. For a phone at this price, it is a minor trade-off, but worth noting if you plan to keep it longer than three years.
Value & verdict
At around €360, the Zero 40 slots into a crowded mid-range category. It earns its price through the 144Hz AMOLED screen and fast 45W charging—two features that genuinely improve daily use and are rare at this cost. The Dimensity 8200 is competent enough that you are not buying last year's performance. The main trade-off is the 1080p resolution on a large screen, which some buyers will notice and others will not; if sharp text matters to you, rivals with 1440p panels are worth considering. The phone also lacks the update longevity of bigger-name brands. For someone in the global south who prioritizes smoothness, brightness, and charging speed over flagship polish, the Zero 40 delivers good value. If you want top-tier display sharpness or the longest support promise, look elsewhere.
Verdict
The Zero 40 suits buyers who spend time outdoors (the bright screen is a genuine win), game casually, and want a thin phone that charges quickly without flagship costs. Anyone prioritizing display clarity on a large screen or expecting three-plus years of software updates should cross-shop rivals with 1440p panels and longer support windows.
- 144Hz AMOLED screen at 1300 nits peak brightness—genuinely readable outdoors and buttery smooth for scrolling
- 45W wired charging hits 60% in 25 minutes; roughly 40–50 minutes to full is faster than most rivals in this price tier
- Thin (7.9mm) and light (195g) without feeling fragile, with IP54 dust and water resistance
- Dimensity 8200 Ultimate handles gaming (Genshin, Call of Duty Mobile) at high settings without throttling; future-proofs better than entry chips
- 1080p resolution on a 6.78-inch screen (393 ppi) means text and icons are noticeably softer than 1440p panels rivals offer at the same €360 price
- Wireless charging maxes out at 20W, which is slow relative to the flagship-tier wired speed
- Only two years of guaranteed major Android updates, shorter than flagship commitments
